The Meerwein-Ponndorf-Verley (MPV) reaction is an important chemoselective route for carbonyl group hydrogenation, and thus designing new and effective catalysts for this transformation remains important and challenging. In this work, a new sulfonate coordinated Zr(IV) catalyst was prepared by the coordination of Zr(IV) onto the sulfonate groups of Amberlyst-15, which can effectively catalyze the MPV reaction and quantitatively convert carbonyl compounds to the corresponding alcohols with high reactivity and stability. Detailed mechanistic investigations reveal that the catalytic performance of Zr-AIER can be attributed to the synergetic effect between Zr and the sulfonate group, and the porous structure with high surface area.
米尔温-庞多夫-韦利（MPV）反应是羰基氢化的重要化学选择性途径，因此设计用于这种转化的新型高效催化剂仍然既重要又具有挑战性。在这项工作中，通过将Zr（IV）配位到Amberlyst-15的磺酸基团上制备了一种新型磺酸根配位Zr（IV）催化剂，该催化剂可以有效催化MPV反应，并以高反应活性和稳定性将羰基化合物定量转化为相应的醇。详细的机理研究表明，Zr-AIER的催化性能可归因于Zr与磺酸基团之间的协同作用以及具有高比表面积的多孔结构。
